Description

Reinforced thermoplastics tubing and production method thereof
Technical field
The present invention relates to a kind of reinforced thermoplastics tubing and production method thereof.
Background technique
Reinforced plastic tubing has two big classes, and the first kind is a reinforced thermosetting plastics tubing, promptly common alleged frp pipe; Second class is a reinforced thermoplastics tubing.The disadvantage of frp pipe is to coil, and therefore, lays and transport all very inconvenient.At present, reinforced thermoplastics tubing mainly is to use Steel Skeleton, hole pattern slab skeleton or steel wire twine, to thermoplastic plastic pipe (for example, polyethylene or polypropylene plastics tubing) strengthen, but, the plastic tube of Zeng Qianging like this, owing to have bigger and uneven internal stress between steel and the plastics, strengthen DeGrain, but also have the connection of tube and tube, butt joint, problems such as end-blocking, simultaneously, because traditional hdpe pipe inner wall surface is crude, very easily cause to be transferred material fouling and constantly thickening, and then stop up, become the main cause that finally causes pipe to be scrapped.Pipe regeneration after scrapping is poor, also can impact environment.A kind of reinforced thermoplastics tubing is arranged at present, and it is with the reinforcing material of fiber as thermoplastic plastic pipe.These fibers are synthetic fiber, glass fibre, carbon fiber or aramid fibre, and wherein, what the enhancing effect was best is aramid fibre.But the price of this fiber is tens of times of plastics, therefore, is difficult to promote in developing country.
Summary of the invention

1. in proportion with nanometer material, antioxidant, paraffin and high-density polyethylene resin, disperse through being equipped with ultraviolet emission device or microwave launcher and the moving dry runner of not stopping transport simultaneously, then, enter tablet machine and make master batch, this moment, the paraffin of super fatting agent effect volatilized fully;
2. in extruder, the master batch that 1. step is made, anti-static agent and high-density polyethylene resin are squeezed into tubing together in proportion, are internal layer;
3. with complex polyester monofilament, rope, band or fabric, on the internal layer surface, positive and negative intersection is twined or spiral twines one or more layers with Stetch Wrapping Machine, forms middle level composite polyester fiber layer;
4. to middle level composite polyester fiber laminar surface heat setting, then, coated with adhesive is with middle level composite polyester fiber layer, and is fixing with internal layer surface bonding;
5. the tubing that is adhesively fixed with middle level composite polyester fiber layer that 4. makes by step, during once more by extruder, the master batch that 1. step is made, ultraviolet protecting agent, high-density polyethylene resin push the surface that is combined in middle level composite polyester fiber layer together in proportion, form outerly, obtain having internal layer after the cooling, middle level and outer three-decker and compoundly be the reinforced thermoplastics tubing of one.
The production method of above-mentioned reinforced thermoplastics tubing, described nanometer material are one or more in nano level calcium carbonate, silica or the zine oxide.
The weight ratio that 1. production method of above-mentioned reinforced thermoplastics tubing, its step prepare the used nanometer material of master batch, antioxidant, paraffin and high-density polyethylene resin is 20: 1.5: 5.0: 78.5.
